UNITED, STATES PATENT o Fics PANEL roa MOLD WALLS Application filedJanuary 26, 1329. 'Serialiio. ,212.

The present invention pertains to a novel panel used in assembling thewall of a mold into which concrete is to be poured.

The principal object of the invention is to provide a panel of thischaracter which, when used in conjunction with aseries of like panels,provides leak-proof joints at the abutting edges of contiguous panels.\Vith this object in view the panel; is provided. with fiat stripssecured at certain edges thereof and projecting beyond the same,while atthe remaining edges are secured so-called receiving strips set back fromthese edges and spaced from the general plane of the panel except forthe points of connection thereto. The panels are assembled in such amanner that the projecting strips of one unit are received beneath thereceiving strips of the adjacent units. i

Another object of the invention is to prevent the device from becominguseless when concrete collects and sets beneath the receiving strips.The points of connection between the panel proper and the receivingstrips are spaced from one another, so that the entire receiving stripis spaced from the panel except at such points of connection. Thus,

when a projecting strip is inserted with some force beneath a receivingstrip, any concrete which may have accumulated under the latter will bethrown out at the inner edge of the receiving strip.

The invention is fully disclosed by way of example in the followingdescription and in the accompanying drawing, in which- Figure 1 is aplan View of a panel accord ing to the invention;

F'g. 2 is a sectional View of an assembled mold t Fig. 3 is an edge viewof the panel;

Fi 4 is a detail section of a joint between panels; a

Fig. 5 is a detail sectional view of an irregular wall; and i Fig. 6 isa detail section of a modifiedjoint.

Reference to these views will now be made by use of like characterswhich are employed to designate corresponding parts throughout.

The body of the panel consists of a metal sheet l,.or even a board, ofrectangular or other desiredshape. At two of theadjacent edges aresecured flat strips 2 which project beyond such edges as clearly shownin Figures 1, 2 and 4. The attachment maybe made by welding for exampleas indicated by the weldspots 3. i j j At the remaining edges of thepanel are secured so-called receiving strips 4 in such a. manner as tobe generally spaced from the" surface ofthe panel. Attachment inthismanner is made possible bystriking depressions 5 at intervals along thestrip and scour ing these depressions to the panel by welding asindicated by the weld spots 7 The receiving strips are set had: slightlyfrom the edges at which they are secured,and the outermost edges otthestrips arepreferably bent slightly away from the panel as indicated bythe numeral 8, for a purpose which will presently appear. 7 j

When aniold wall is assembled from such panels, they are arranged sothat the pro cated by the numeral S), andwhe'n these edges are broughttogether, the projecting fiat strips 2 pass beneaththe outer edges ofthe receiving strips'4 as shown more clearly in strips facilitate entryof the projecting strips.

The abutting edges of the panels 1 may, however, be cut square as at 9in Figure 6 to form a simple butt ]O1Ilt.

Figure 4} The bent edges 8 of the receiving" Due to the almost completespacing of the a strips 4 from the panel, any concrete which may haveaccumulated beneath these strips in previous use may be. broken loose bya forcible insertion of the strip 2, whereupon the loose chunksotmaterial are enabled to fall away'by passing beneath the inner edges ofthestrips. It will be evident that such release and expulsion ofaccumulated material would not be possible if the strips 4 were notspaced almost entirely from the respective panels.

In Figure 5 is illustrated a construction wherein the mold wall hasdihedral angles.

Via

Such angles are formed by providing angular projecting strips 10 at oneof the sides 11 thereof in such a manner as to be inserted beneathreceiving strips 12 secured to the panel 13 constituting the other sideof the angle, in the manner already set forth.

Although specific embodiments of the invention have been illustrated anddescribed, it will be understood that various alterations in the detailsof construction may be made without departing from the scope of theinvention as indicated by the appended claims.

IVhat I claim is 1. In a panel for a mold Wall, a strip secured at anedge of said panel, and a receiving strip secured to another edge bymeans of spacers, whereby said receving strip is spaced from said panel,said spacers being spaced from each other.

2-. In a panel for a mold wall, a strip secured at one edge of saidpanel and projecting from said edge, and a receiving strip secured bymeans of spacers at another edge of said panel, whereby said receivingstrip is spaced from said panel, said spacers being spaced from eachother, and said receiving strip being set back from the edge at which itis secured.

3. In apanel for a mold wall. strips secured to said panel at twoadjacent edges thereof, and receiving strips secured by means of spacersat the remaining edges of said panel, said spacers being spaced fromeach other.

4. In a panel for a mold wall, strips secured to said panel at twoadjacent edges thereof, receiving strips secured by means of spacers atthe remaining edges of said panel, said spacers being spaced from eachother, said first named strips projecting beyond the edges at which theyare secured, and said receiving strips being set back from the ed es atwhich they are secured.

5. In a panel for a mold wall, a strip secured at an edge o1 said panel,and a receiving strip having spaced projections extending toward saidpanel and secured at another edge of said panel, whereby the majorportion of said receiving strip is spaced from said panel.

6. In a panel for a mold wall, a strip secured at an edge of said panel,a receiving strip having spaced projections extending toward said paneland secured at another edge of said panel, whereby the major portion ofsaid receiving strip is spaced from said panel, said first named stripprojecting beyond the edge at which it is secured, and said receivingstrip being set back from the edge at which it is secured.

In testimony whereof I afiix my signature.

FRANK J. GREMEL.
